I usually don’t post anything with my photos, besides tagging them, but I had to say something about this lady. I was curious about her so I googled her name and found out that she wasn’t just a pretty face. According to Wikipedia:

Justine Johnstone was an American stage and silent screen actress who retired to become a pathologist and expert on syphilis.

After giving up performing, Johnstone enrolled in Columbia University, where she studied plant research and served as a research assistant to Samuel Hirschberg and Harold T. Hyman. With them she was partner in the development of the modern I.V. unit. She later studied and made developments in endocrinology and cancer research and installed a laboratory in her house in Hollywood.
